| 摘 要： | 通过对散射板干涉位的适当改型，利用散射板上高轮点产生的附加程基来补偿球面和非球面之间的光程基，无需任何零光学元件，就可产生一种新型的二次非球面零测试法。本文对这一方法进行了描述、分析和实验。

| Abstract: | A new kind scatter plate interferometer which achieved null-testing of aspheri-cal surface. The approach makes use of a large aperture scatter plate for compensating theoptical path differences between spherical and aspherical surface, needn't any null optical el-ements. This paper describes the method principle and give a testing. |
